The results of the multiple logistic regression analysis on obesity (defined as waist circumference 85+ cm17) in the 4th quartile (total: 74, without polymorphism: 48, with polymorphism: 26) are shown in Table 5, in which the presence of ADRB3 polymorphism, smoking, age and physical activity were independent variables. Here, ADRB3 is linked to obesity disorder.
